Terms and dictionaries and thirty years.

I once wrote to a reputable dictionary company to inform the editors of a word-use I'd never seen or heard before that wasn't in their dictionary.

I was speaking with an old trapper in northern Alberta asking after his success the previous day. I don't recall exactly, but our conversation went something like

Me: Good day yesterday?
He: Uh. (Meaning 'not great'.)
Me: How many lynx you take?
He: [Held up his forefinger to designate 'one'.]
Me: Uh. (Meaning 'oh, that's too bad'.)
He: Uh. (Meaning 'you got that right'.)

I didn't pursue it at the time because he'd chosen trapping as his way of life and he didn't need someone having long talks with him, and I'd already pushed that limit.

The dictionary people informed me that words are not entered in their dictionary until after they have appeared in print. (I don't know if that applies in the case you mention.)
